AS Ranges for Dynamic BGP Peer Groups

BGP neighbors, or peers, are initiated by configuration commands that cause BGP to establish TCP connections with other BGP speakers.  Dynamic neighbors are established by creating a listen range and accepting incoming connections from neighbors within that address range.  Dynamic neighbors must be configured using a dynamic peer group, which defines attributes for all neighbors associated with the listen range.  A BGP listen range has so far allowed exactly 1 remote AS number to be specified for acceptable incoming connections. The AS Ranges for Dynamic Peer Groups feature introduces a flexible means of specifying multiple, allowable remote AS numbers for...

802.1br-E/VN Tag Stripping

This article describes a Tap Aggregation feature to strip IEEE 802.1BR E-Tag and Cisco VN-Tag headers from all tagged packets received on any tap interface before delivering them to tool interfaces. Untagged packets are unaffected. This feature may be useful for third-party tools and/or packet analyzers which cannot parse these headers. Platform Compatibility DCS-7280E/R series DCS-7500E/R series Configuration By default, Arista switches do not strip BR-E/VN tags from ingress packets. BR-E/VN tag stripping is globally configured for Tap Aggregation. The feature allows a choice of stripping both or either of the tags. To enable BR E-Tag stripping add the following configuration: Arista(config)#tap aggregation Arista(config-tap-agg)#encapsulation dot1br strip To enable...
